TIRE-SUPPORT.

Specification of Letters Patent.

Patented Sept. 9, 19153.

Application filed March 3, 1913 Serial N 0. 7 51,853.

Be it known that I, Louis E. CADWELL, a. citizen of the United; States, and a 'resicity, New York, have in- Vented certain new and useful Improvemerits. in Tire-Supports, of which the fol-- lowing is a specification. y improvements relate to automobile tires, particularly those known as demountable rim tires, the object being ective means for in position upon the support, and to utilize the area. inclosed Y hy said support.

Tot-his end'the invention-consists the specific construction and arrangement of parts described and claimed, a distinctive feature being the use of an ex'pansible drum. section over and upon the peripheral surface of'which a demonntable rim tire may supports. for, I

quired, the invention also including certain In the accompanying drawings, F igure my improved tire support; Fig. 2, a side elevation of the l same; F ig. 8, a front elevation of my tire support, showing a demountable rim tire in position thereon; Fig. 4, a side elevation of my tire support with two tires in position; Fig.5, is. a horizontal section taken HPOII'; line 55 F ig. 3; Fig; 6, a vertical section taken upon-line 6-6 Fig. 1; Fig. 7. is a sectional view taken upon line 7-7 Fig. 4; Fig. 8 is a sectional detail. of one of the bracket clamps; Figs. 9 and 10, are respecti-vely side and top views of means of adjustment adapted for usein connection with The fundamental or basic member of my demountable rim tire holder or support is the expansible drum section a. This is esse-ntially and in its simplest form a cylindrical plate of, say, approximately five sixths circumferential extension, the other one sii'ih "representing the space between the two ends of the plate, which is supported on brackets b, b, protruding from any suitable support, as may be found expedient. As appliedto, automobiles, I prefer to attach the brackets 6; ZS, to the frame or.

which are shown in the drawings,

may be readily expanded chassis of the machine, although this is not an essential matter. The brackets 25, b, the forward rod-like ends or arms only of are secured to the expansible drum a, hy any suitahle means, as by clamps a, c, and said bracket arms afford suiiicient elasticity and resilience to enable them to yield to the Justment of the eXpansible drum (2, the excomparanot more than one fourth at the ends of the drum tent of such adjustment being tively slight and In order to afford a smooth uniform'peripheral surface onthe drum a, for the accommodation ofa demountable rim r, of a tire, I prefer to secure the clamps c, c, to

L the inner side of-the drum plate a, as shown in Fig. ,8, the metal of .the plate being inset to form sockets a, a, for the reception of the heads of the-:bolts c, c, which heads are thus practically countersunk in q the drum plate a. This construction not 1 incidental. features hereinafter fully set' forth.

only leaves drum surface, tute a bolt or an unobstructed peripheral but it enables me to substinut when necessary without discarding or mutilating the clamp itself.

The drum section a, is expanded or contracted sufiicientl y to clamp or release a dcmountable rim tire placed thereon by any suitable and Well known mechanical expeclient, as by the use of the coupling rod cl, rigidly secured to one extremity of the drum plate a, and adjustably secured to the other extremity of the said plate by means I of a swivel nut d, 5011 the plate a,

threaded end of mounted on, a bracket a and engaging with the By this or equivalent means of adjustment the drum plate a,

tightly fit andfirmly secure a demountable rim tire positioned thereon, or quickly contracted to release said tire. In this connection it may be noted that the drum plate is preferably made wide enough to accommodate two demountable rim tires, and hence by merely tightening or loosening the swivel nut d", upon the coupling; rod a, both tires may be secured or released. The

space below the coupling rod 01, between the enfls'of the drumplat'e a, afiords ample the coupling rod d, as. :shown more particularly in Figs. 9 and ill of the drawings.

when secured to the drum a, by the expansion of the latter so that its peripheral surface binds tightly against the inner surtace of the'demountable rim 9, the tire is held rigidly in position, so that there is no vibration or loose play of parts to wear and deteriorate the tire, its cover &c., not to mention the elimination of rattle and noise.

Obviously my expansible tire-supporting] e used without accessories other than those hereinbefore set, forth, but I prefer to utilize the area circumscribed by the drum plate a, as a receptacle for various articles, and to this'end I form the drum plate a, with inturned edge flanges a, a, to which are attached back plates a a and lhe back plates a a are offset to overlap at their opposed edges, as indicated in'llig. 5, or otherwisemade to allow and compensate for the slight movement involved in the adjustment of the drum plate a, by means of the coupling rod (Z, and nut d, Between the vertical edges of the front plates of, a, are mounted sliding doors e, e,-the vertical edges" of which rest in grooves formed by angle plates a, a, (shown in Figi h) on the vertical. edges of the front plates a, a, said grooves being of sufficient depth to allow for theadjust;

ment of the drum plate. The lower door a,

when raised, gives access to the swivel nut d, &c., for thepurpose of effecting the ex pansion or contraction of the drum plate;

and the upper door a, when lowered, gives accessto the inclose'd space above the shelf k,

which is situated above the coupling rod. d, and connections. Thisshelf it, maybe rig idly supported on, one side of the drum plate a, and sli'dablysupported on the'other side thereof, 'as shown more particularly iIiFigw 7, so as not to interfere with the adjustment of-the' drum plate; and it affords a convert} ient support for articles suitable to be stored within the receptacle thus created without in the least impairing the function of, the drum plate as a'positive means for rigidly supporting one or inore demountable rim The doors e, e may be secured in their a closed relation to each other by locking means, as by the use of what is known as a trunk lock t, indicated in Figs. 1, 3 and 6. :I am aware that independent circular" trunks have been inserted in tires o'herwise supported, but such are not the equivalent of my unitary demountable rim tire holder and receptacle, of which latter the adjustable drum plate forms a component -part,and

the other arts of the receptacle being adapted to con orm to the movement of the drum plate 'as hereinbefore set forth. Furthermore my expandable and contractable drum plate is a most simple but effective device for effecting the rigid support of one or more demountable rim tires and attaining the quick and convenient release thereof when desired, a few turns of the swivel nut a3, being suflicient for either purpose. It practically eliminates vibration, the chafing of retaining straps, tire covers, &c., and adds materially to the comfort and convenience of automobili'st's.

By the use of the term drum plate herein it is to be understood that I mean an approximately cylindrical structure of less than full circumference, having free ends opposed to each other below the axial center of the structure,-or in other words, an approximately annular plate the ends of which are separa-ted to a certain extent.

The incasing of the expansible drum plate, and the locking of the inclosing doors perform another important function in that the tires are thereby safeguarded against surreptitious removal. since they cannot be loosenedordetached until the doors are unlocked, What I claim as my invention and desire to secure by Letters Patent is,

1'. A support for demountable rim tires comprising a drum plate, the free ends of which are united by means by which the drum may be expanded to bind against the inner'surface of the detachable rim, or contracted to release the said rim.

21A support for demountable rim tires consisting of .an approximately annular drum plate, and means for expanding and contracting the same to bind or release the rim positioned thereon. I

3. A support for demountable rim tires comprising an expandable and contractable drum plate, means for expanding and con-. tracti'ng the same, back plates attached to said drum plate and formed with overlappingand contacting edges, front plates attachedto said drum plate, and doors slidable between said front plates, for the purpose described, i
